To all whom. it may concern Be it known that I, JEAN Bsr'rrs'rn MARIE PIERRE HENRY ROSLIN nlvnr, of Paris, Republic of France, have invented Improvements Relating to Electromagnetic Receivin Apparatus of which the following is a f1 clear, and exact description.

I The present invention relates to an electro magnetic receiving apparatus.

The essential feature of this apparatus is to provide a device for insuring the distri bution of the current in the utilization cir cuit, while at the some time retarding the contact in order to enable a contact lztey pass over the several tin-utilized contents without closing the electric circuit.

The invention is hereinafter described with reference to the accompanying drew ing, in which Figure 1 shows in elevation, partly sec tion the part for the distribution of the current, which at the some time provides the necessary retardation in the contact the employment of an approp iate liquid. Fig. 2 is a: plan view thereof. Fig. 3 is a vertical sectional view. Fig.4 a vertical sectional view showing the parts raised position. Fig. 5 shows in elevation a device for the distribution of the current, which at the same time provides for the retardation of the contact by means of air.

Fig. 'l' is a. vertical sectional view of the device shown in Fig. 5.

The distributing part which is shown in Figs. 1 to 4, utilizes an appropriate liquid such as petroleum for example. This part comprises broadly a coil a capable of attracting a core of soft iron I; which is movably mounted on a central guide a in such it manner that it may ascend and descend inside of a movable cylinder (Z which is arranged in a tube e fixed to the coil (1 The movable cylinder (Z is provided at its lower end with two studs f which are chamfered and arranged diametrically opposite one another. This cylinder 0? is surmounted by a rod d which passes through a soft iron. plug 9 and carries a cross piece d forming a contact key, The cross piece is fixed to therod by a metal-nut h surmounted by a screw cap 71 of appropriate insulating material:

1n the cully arranged chomiered studs j. The upper studs 7' and the lower studs f are errunged opposite toothed c'cwns e" e which are formed on the upper and lower extremities of the tnhc e, The teeth of one crown are cut in the opposite direction to the teeth of the other crown. It follows from this orrangement that the vertical movements of the cylinder d will cause the rotation of the cylinder of end of the key (Z which is carried hereby. l

The key is provided at one extremity with spring contact piece (Z which isudeptcd to rest on the contacts 7a of an cbonitc crown '2 so as to close on electric circuit to the member winch-it engages. In. order that t 1e rev may move from one contact to another, it necessary that the cylinder (Z should move up and down so that the teeth may rotate the cylinder carrying the l' i All the contacts are provided with terminals m radiating around the ehonite crcwn 5 from which the ircs of the various circuits leedl i The contact r tnrding dev'ce. which con oiled by i of n liq. colnpri a cup n contf a certain quantity of petroleum into which the lower ot the guide 0e: ends. This guide is mounted on an ehonite washer owhich is comiected with the lacs. 39 of the device by means of rods The guide c is tulniler and coinpri lower end a hell suction valve r ietcre discharge orifice s, which is adjustable by means oi a pin screw .9. .his s row serves two purposes: let it serves to Ififali'l the ball r; 2nd, it is intended to serve as a controller of the escape of the liquid contained in the tube. by reason of the feet that the extremity of the screw, which is in the form of a point, penetrates more or less into the hole .9 which is exactly opposite this screw.

Two lugs t depending from the ring 26- limit the downward movement of the core 7).- The ring it is electrically connected to the base by means of ewire 'w A part 41* forms a. screen for retarding the flow of the liquid through the discharge orifice s. This device being interposed in the circuit of a suitable relay, each time that current is caused to flow through the coil a by the transmitting mechanism which is connected to terminicls H and III, the core Z; ahdthc cylinder 66 are caused toner-end gravity,

During the ascent; of the core Z7 and the cylinder (Z, the ball a will have risen, owing to the suction pro.

duced, thus permitting the liquid. in the cup at to pass into and through the tubular guide 0 to fill the core I). This core Z) being full of liquid is maintained raised and is unable to descend together with the cylinder (Z, except in proportion to the flow oi? the liquid through the discharge orifice s, the cross section of which may be modified by means of the said pin screw. During the upward movement of the cylinder d, the lower studs f encounted the toothed crown e and cause the cylinder (Z to rotate, thus advancing the arm (Z? halt the distance that separates one contact 7i; from the following one upon the crown Z.

l/Vhen the current. ceases to act upon the solenoid a, the cylinder (Z descends again by and the upper studs 9' encountering the, teeth of the upper crown (2. impart a rotary motion to "the cylinder .cZ, causing the the remaining half of the order to allow the contact piece 03 to engage that contact Which is next to the one which it engaged atthebeginning of the upward movement of the cylinder 03.

The advancement of the arm or key (1Z from one contact to another takes place t on in two different periods; first period, during the rise of the cylinder d; second period, during the descent of the cylinder d.

Owing to 'the retarding action pf the liquid, the core I) Will not reachllthe end of its downward movement until some time after the cylinder (Z has its lowermost position.

When the core I) has completed its down ward movement the lugs 25 will rest upon the circular block'o' .and the current of utilization passes from the terminal .lV through the Wire 10 toblock 0 to studs t to the cylinder (Z,'-.t-hence by way of (Z and (Z to the contact piece (Z and then by way of that one of the terminals m which is joined to that particular one of the contacts which corresponds to the chosen control.

From the terminal m the current. of utilization goes to the appa atus or to the 1nachine which is to be setinto action, and returns from this machine to the source of electricity by way of a return-wire.

The core I) remaining raised, as just stated, the closing of the circuit will. not

,to 7, the contact is rctardod by the employment of air instead of a liquid. .hen the core 7) is attracted, the air in the cylinder (Z escapes through the'ball valve 2 until the core strikes against a ...'cstriction formed in the cylinder, in order to produce the ascentof this cylinder in the tube 0. The core Z) is only able to descend by virtue of gravity in proportion as the air reentcrs the cylinder (Z whereby the retardation of the contact is obtained. The duration out this retardation is regulated by means of a pin screw 2 enabling the air to reenter the cylinder a? more or less rapidly. It will, of course, be understood that the said retardation might be obtained by a different arrangement.

In its lower position the core rests, Ly means of a tail piece Z) on a small metal block 0 fixed at the center of the washer 0 of the insulating material.
